Research on Matching Costs for the Stereo Algorithm

My undergraduate thesis at Seoul National University, where I built an artificial neural network that combined multiple stereo vision matching algorithms to produce more accurate depth maps than any single algorithm could achieve on its own.

IEEE IoT Newsletter: "Divide and Conquer: How Edge Processing Will Open a New Door for IoT Applications"

Berlin, Germany

An article I wrote for the IEEE IoT Newsletter, making the case for edge computing, arguing that as IoT devices multiply and generate more data than the cloud can handle in real time, pushing processing closer to the device isn't just a nice-to-have, it's the only path forward.

Diagram showing the connection between edge computing and smart technology applications such as factories, retail stores, vehicles, and smart homes, with devices like smartphones, smartwatches, IoT sensors, and IoT OPFs.
